Services like Netflix, Hulu Plus, and Amazon Instant are great for catching up on your movies and TV on demand, but they all have different selections. Moki.tv searches all the popular movie and TV show outlets from one, unified engine.

Moki.tv aggregates both paid and free content into its humungous directory, boasting over 40,000 movies and 60,000 TV shows. Not only can you search for what you want to watch, but you can import your Netflix ratings, get recommendations, and even get alerted to when certain movies or TV shows become available for streaming online. It's not unlike previously mentionedClicker, though I much prefer Moki's interface, and it seems to offer more suggestions (Clicker has left Hulu out of my search results before, even when an episode is available on it).
